Subtypes in Databases: backend_platform — bundles a database with auth, functions or storage as one product. We read that on 2026-08-31 from https://www.convex.dev/, where it says: “Convex is the reactive backend platform that keeps up with you and your agents.” How we use this.

How Convex compares against every one of the 8 we list, not against a selection of them. A surface with room for every member of a tied set may rotate their order. A surface with room for only some of them names none of them, because which ones it named would be the claim, and a claim seeded on the date is not the one we serve tomorrow. How we decide this.

Supabase	Free Postgres development platform: database, Auth, Storage, Realtime and Edge Functions. The Free plan is $0: unlimited API requests, 50,000 monthly active users, a 500 MB database on a shared CPU with 500 MB RAM, 5 GB egress plus 5 GB cached egress, 1 GB file storage, 500,000 Edge Function…	stable
Nhost	Free Open-source backend with Postgres and Hasura GraphQL, plus Auth, Storage and Functions. The Starter plan is $0 a month: 1 GB database, 1 GB storage and 5 GB egress, with functions, realtime APIs and unlimited users.	stable
Appwrite Cloud	Free Open-source BaaS — 75K MAU, 2 GB storage, 750K function executions/month, 5 GB bandwidth, 1 database, 1 bucket and 2 functions per project, 500K database reads and 250K writes a month. Limit of 2 projects. The Free plan's resources are shared across the account's 2 projects, which draw on one allowance. Paid plans give each project its own resources. (From appwrite.io/docs/advanced/billing/free, read 2026-10-11.) A Free project with no development activity in the Appwrite Console for 7 days is paused. User traffic does not prevent pausing. The project becomes inaccessible to users and stops running backups, cron jobs, and scheduled functions until reactivated in the Console. (From appwrite.io/changelog/entry/2026-02-20-1, read 2026-10-11.) Free projects are deleted after 90 days paused. (From appwrite.io/changelog/entry/2026-06-29, read 2026-10-05.) From October 19, 2026, cron schedules for functions on Appwrite Cloud need a paid plan. On the Free and Education plans, functions run only on an interval of 60 minutes or longer. Existing cron schedules become intervals close to how often they ran. (From appwrite.io/changelog/entry/2026-10-15-1, read 2026-10-19.) If a Free project reaches any resource limit, such as function executions or monthly active users, it freezes and the Console becomes read-only until the next billing cycle, or the owner upgrades to Pro or removes the resources over the limit. (From appwrite.io/pricing, read 2026-10-05.) From November 5, 2026, Appwrite Cloud deletes inactive function and site deployments more than 30 days old by default. A deployment's age counts from the day it was created. The active deployment and any deployment a custom domain points to are kept. On the Free plan, retention can be raised to at most 90 days and each function or site keeps at most its 100 newest inactive deployments. (From appwrite.io/blog/post/default-deployment-retention, read 2026-10-22.) On the Free plan, inactive deployments count toward the same 2 GB of storage as files and databases. (From appwrite.io/blog/post/default-deployment-retention, read 2026-10-22.) Pro starts at $25 a month. It includes one project with 2TB bandwidth, 150GB storage, 3.5M executions and 200K monthly active users. Each additional project costs $15. (From appwrite.io/pricing, read 2026-10-29.) Additional API bandwidth costs $15 per 100GB a month. Additional storage costs $2.8 per 100GB. Additional executions cost $2 per 1m. Additional users cost $3 per 1,000 users. Additional reads cost $0.060 per 100k and writes $0.10 per 100k. (From appwrite.io/pricing, read 2026-10-29.) On Pro, Appwrite automatically buys extra resources when an organization exceeds its limits. The budget cap limits how much it can scale. (From appwrite.io/docs/advanced/billing/pro, read 2026-10-29.)	caution
